IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 153,381, dated July 21,1874; application filed July 1,1874.

. Faught, February 20, 1872: and the nature of my invention consistsiirtlie construction of the devices whereby the large drivingwheel ofthe horse-power is secured to the hollow upright post or column. It alsoconsists in constructing the hearings or supports .for the upper end ofthe central support and for the inner end of the horizontal shaft of onepiece, all as hereinafter more fully set forth.

In order to enable others skilled in the art to which 111 y inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a longitudinal section of a horsepower embodying myinvention, and Fig. 2 is a side view of a part thereof, showing theconnection between the wheel and hollow upright column.

A represents the central support, which may be a solid post or tubularcolumn, and is supported by its lower end in a socket in the step-plateB, constructed in such a manner as to keep the post from turning. Theupper end of the post A is held in a casting, O, attached to the timbersof the floor above, so that the post A will form a support for the same.Around the central post A is placed a hollow shaft or column, D, whichrests upon the step-plate B, the adjoining surfaces being made flat andchilled, so that the hollow shaft will revolve on the step-plate, andthere being no liability of dirt getting in between the surfaces to wearthem. The upper end of the hollow shaft D is made polygonal-shaped onits outer circumference, and immediately below this part is formed acircumferential collar, to. E represents a plate placed over the end ofthe hollow shaft D and resting on the collar a, to which it is securedby bolts 1) passing through the collar and through ears projecting fromthe collar. On the upper surface of the plate E are situated flanges d(1, arranged in pairs to form in connection with corresponding flanges dd on the under side of the top plate Gr, mortises or guides for theinsertion of the inner ends of the arms II II of the wheel. The plate Gis also made to fit the polygonal-shaped upper end of the hollow shaft1), and covers said end thereof. The plates E and Gr are fastenedtogether by means of bolts e e, which also pass through the arms H H,and thus securethe whole together. The wheel, of which the arms H form apart, is constructed in the usual manner, with rim I and braces J J, anda cogged ring, h, attached to, or forming part of, the rim. The coggedring it gears with a pinion, f, upon the horizontal shaft L. The bearing11 for the inner end of this shaft L is formed in the casting G, whichwill insure said shaft being always in line.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The flanged plates E and G, in combination with the hollow shaft orcolumn D, having collar a and made polygonal-shaped above said collar,the arms H H, and the bolts 1) and c, all substantially as and for thepurposes herein set forth. 2. In a horse-power, the casting Q, formingthe upper rest for the central support A, having the bearingt' for theinner end of the horizontal shaft L, formed therewith, substantially asand for the purposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my handthis 1st day of July, 1874.
